Comodo Firewall Vulnerability

Comodo Firewall Pro (former Comodo Personal Firewall) stores some of its internal settings in the registry key HKLM\SYSTEM\Software\Comodo\Personal Firewall. This key is protected by Comodo drivers such that other applications are not able to change the settings. This protection can be bypassed if very special conditions are met. CFP internally uses a named pipe, which name varies, but can be always determined. A process that opens this pipe many times is able to manipulate the protected settings of CFP. A proper modification of the settings will disable all protection mechanisms implemented by CFP after a reboot.
